Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, and more specifically, to a circulating grinding device for ore processing. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which possesses certain usable properties. Mined ore needs to be processed, and this process involves grinding the ore.

[0003] A search revealed a utility model patent with publication number CN217093698U, which discloses a grinding and screening device for ore processing. The device includes a housing with a feed pipe and a discharge pipe, and a grading grinding section and a screening section. The grading grinding section includes a rotating shaft rotatably connected to the top wall of the housing. A grinding block is fixed to the bottom of the shaft, and a grinding shell with through holes is provided on the outer side of the grinding block inside the housing. The inner diameter of the grinding shell decreases from top to bottom, and the top of the grinding shell is dome-shaped. This patent, by incorporating a housing, feed pipe, and grading grinding section, uses a motor to drive the grinding block to rotate, allowing the ore to enter between the grinding block and the grinding shell for grinding. When a finer grinding particle size is required, tightening the locking screw controls the motor to drive two screws to rotate, causing the grinding shell to move upwards. This reduces the gap between the grinding shell and the grinding block, enabling the grinding of finer particles. The device can grind ore of various particle sizes, demonstrating good practicality and grinding effect.

[0004] However, the aforementioned patent has the following shortcomings: although the height of the grinding shell can be adjusted through the cooperation between the support block and the screw, since part of the screw is located above the grinding shell, the screw will come into contact with the ore, which will damage the bolt. At the same time, dust falling on the screw will affect the transmission between it and the support block; and since the screen plate is fixed on the inner wall of the box, only one type of screen plate can be used for screening after grinding ores of different particle sizes, which is not very practical. To address these issues, we propose a circulating grinding device for ore processing. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a circulating grinding device for ore processing.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0012] In a preferred embodiment of this utility model, the inner wall of the lifting box and the side of the lifting column are fitted together.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when it is necessary to adjust the height of the grinding shell, the first motor drives the screw to rotate, and the screw and the grinding shell move up and down through the threaded connection between the screw and the lifting column, thereby adjusting the position between the grinding shell and the grinding roller, and the grinding shell moves up and down through the lifting column, effectively avoiding the impact of the ore on the screw.

[0015] (2) In this utility model, when the ground ore falls onto the screen, the eccentric wheel is driven to rotate by the dual-shaft motor. The centrifugal force of the eccentric wheel drives the arc plate, arc frame and screen to vibrate up and down, so that the ore on the screen can be screened efficiently. After adjusting the grinding outer diameter of the ore, the sealing door can be opened to replace the screen, ensuring that the screen can effectively screen the ground ore.
